Target entity: Nazca–South America plate boundary
Context triple: [Liquiñe-Ofqui Fault Zone, tectonicSetting, Nazca–South America plate boundary]
  • A. Nazca Plate
    The Nazca Plate is an oceanic tectonic plate in the southeastern Pacific that subducts beneath the South American Plate, driving Andean mountain building and frequent earthquakes and volcanism along the western coast of South America.
  • B. Cocos–North America plate boundary
    The Cocos–North America plate boundary is a convergent tectonic margin where the oceanic Cocos Plate subducts beneath the continental North American Plate, generating significant seismic and volcanic activity along Mexico’s Pacific coast.
  • C. Cocos–Nazca spreading center
    The Cocos–Nazca spreading center is a mid-ocean ridge in the eastern Pacific where tectonic divergence forms and separates the Cocos and Nazca plates.
  • D. Farallon–North American plate boundary
    The Farallon–North American plate boundary was an ancient convergent margin along western North America where the Farallon Plate subducted beneath the continent, setting the stage for the modern Pacific–North American plate boundary system.
  • E. Chile Triple Junction
    The Chile Triple Junction is a tectonic plate boundary off the southern coast of Chile where the Nazca, South American, and Antarctic plates meet, creating a complex and geologically active region.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
